This module contains practical examples of Docutils client code.
|
||
|
|
|
||
|
|
Importing this module from client code is not recommended; its contents are
|
||
|
|
subject to change in future Docutils releases. Instead, it is recommended
|
||
|
|
that you copy and paste the parts you need into your own code, modifying as
|
||
|
|
necessary.

|

Given an input string, returns a dictionary of HTML document parts.
|
||
|
|
|
||
|
|
Dictionary keys are the names of parts, and values are Unicode strings;
|
||
|
|
encoding is up to the client.
|
||
|
|
|
||
|
|
Parameters:
|
||
|
|
|
||
|
|
- `input_string`: A multi-line text string; required.
|
||
|
|
- `source_path`: Path to the source file or object. Optional, but useful
|
||
|
|
for diagnostic output (system messages).
|
||
|
|
- `destination_path`: Path to the file or object which will receive the
|
||
|
|
output; optional. Used for determining relative paths (stylesheets,
|
||
|
|
source links, etc.).
|
||
|
|
- `input_encoding`: The encoding of `input_string`. If it is an encoded
|
||
|
|
8-bit string, provide the correct encoding. If it is a Unicode string,
|
||
|
|
use "unicode", the default.
|
||
|
|
- `doctitle`: Disable the promotion of a lone top-level section title to
|
||
|
|
document title (and subsequent section title to document subtitle
|
||
|
|
promotion); enabled by default.
|
||
|
|
- `initial_header_level`: The initial level for header elements (e.g. 1
|
||
|
|
for "<h1>").
